Period or pregnancy?

Hello! I'm currently 8dpo and can't tell if my symptoms are pms or possibly pregnant! My husband and I have been trying for two months now and bd about every other day during my fertile week. I've had extremely sore breast to the point where wearing a bra kills, I've been nauseous the past couple of days, feeling a little sick, low appetite, slight cramps, been mossy beyond belief, very emotional and majorly fatigued Thank you in advance (:
